I'll Drive the Spaceship Directly to the Moon

Ten years ago, an evil exchange student went to study in Country M, but died in the United States three months later. His money disappeared with him. Although the people of Long Country protested later, nothing happened in the end. He was 16 years old that year. Ten years later, this exchange student actually flew to the moon on the Ark he built? It turns out that he obtained the system and the technology to build the Ark spaceship ten years ago, so he used his mind to fake death, and then used his new identity and money to spend 10 years building a spaceship?
